IAMS™ Proactive Health™ Senior Plus Large Breed Dog Food Review

The following review of IAMS™ Proactive Health™ Senior Plus Large Breed dog food covers the information you will need to decide if this is the right food for your senior plus large breed dog.

The lifespan of any beloved dog is far too short. Owners of large breed dogs tend to have even less time with their pets. Generally, larger breeds such as Saint Bernards and Great Danes have the shortest lifespans while small breeds like Chihuahuas or Dachshunds may live more than twice as long. Medium-sized dogs like the Irish setter or Dalmatian usually have a lifespan somewhere in-between. Since some dog owners are passionate about large breed dogs, they want to take every option available to them to keep their dog healthy and active so they can live the longest, best quality of life possible. That starts with feeding them the right food for every phase of life.

As dogs age, they become more susceptible to a number of conditions that make it difficult for them to do many of the things they need to do to keep them healthy. The dog food that you give your dog should be formulated specifically for your dog’s age and breed to compensate for these changes. The right blend of nutrients can go a long way towards preventing some of the signs of aging that large breed dogs encounter.

A Note on Meat Byproducts

There has been a lot of controversy over the use of meat byproducts. This simply means that the food uses bone, stomach, brains, and other parts of animals in the food. Parts of animals that will put dogs at risk of health conditions, such as mad cow disease, are not permitted for use in pet food. Meat byproducts are actually a good source of protein. Instead of worrying over the source of the meat, it is more important to look at the percentage of protein and the additional nutrients in the food.

All dog foods should meet the minimum standards of at least 10% protein, 5.5% fat, and 2.5% crude fiber. This dog food contains significantly more of these vital ingredients for the ultimate nutrition for your aging dog.


IAMS Proactive Health usually costs over $32 for a 26.2-pound bag but dog owners can find the best bargains at Amazon.
